MAOHINE FOB FILLING BOTTLES WITH AERATED WATERS.

To all it may concern:

Be it known that we, WILLIAMFORRESTEB,

siding in Larbert, StirIingshire, Scotland,

. have invented a new and usefulMachinefor or by a large plate carryinga series of cams Filling Bottles with Aerated Watersand the. Like, ofwhichthe following isya full and complete specification. a

The present invention] relates to improvements in machines for fillingbottles with aerated waters, and the like, the machine being of. thattype in which the'filling devices are mounted on o. tablerotated bypower, or hand, the objectbeing to simplify the construction of such'machines, render them more automatic, and to rovide, an im roveddevicefor regulating t e amount of iquid supplied to the bottle, wherebythe operation knownas sniftingYis obviated.

We are aware that it has heretofore been roposed in the construction ofmachines orming the. subject matter of the present invention to form thefilli head or cup for receiving the mouth of the ttle in one with thevalve chamber containing the valve for.

controlling the supply of fluid, while others have been arranged withthe fillinghead and valve chamber separate, in both. cases, how. ever,the valves. are either operated by hand ada ted to .0 en and close suchvalves at pre etermine periods, but this. form 05 device isobjectionable in that should a bottle break, the liquid bei suppliedmustflow away and be lost until theoperator closes same by hand or. acam comesintoposition to close the valve in the latter case, however,

unless thewhole machine is stopped, or a new; bottle immediately placedinthe machine, ain flowto waste when the liquid would another cam openethe valve. In this form of machine it is also necessary to have a bottlein each holder-while the machine is in motion, otherwise the fluid wouldgo to waste each time the valve of the articular empty holder wasopened. Means ave also been proposed for normally maintaining the supplyvalves closed or for automatically closing such valves should a bottlebreak, such meanswbeingopcrated in some cases by devices connected tothe bottle holder, while others have been op eratedby means contained inthe filling head itself. Means have heretofore been proposedforSpecification of Ilettera Patent. Application tiled April s, ieos." armin. 4mm;-

regulating the amount offluid supplied, thereby obviating the operationof snift'ing,

consisting of a chamber placed between the valve and the mouth of thebottle, having a piston, formed of cup leathers, sliding there incarried by a screwed pistonrodoperated i from the top of the c inder,the cylinder has, however, to be c small diameter and of somelength'owing to the restricted posi .tion and close proximity of the dischargevalves, thus necessitating a considerable movement of the piston rod toeffect any a preciable alteration in the capacity of t 1e cylinder, and,should the cup leathers get dry,-leakage of air results. The presentinvention broadly co "sist's in opening with a separate cam plate,providing means for automatically operating'such cam plates, means forautomatically closing any one or'moreof such valvesshouldla bottle beproviding each valve controlling a discharge broken, or if a-particularfiller bevacant, an d an improved form of chamber for regulating jarranging the valve controlling the-discharge of the fluid'in thefillinghead itself,"and the top of'the head isshaped'so as to permit a.cam plate torfreely rotate thereon whenthe same is automaticallyoperated by means,

suchas a suitably supported roller, carried radially.arrangedrolleradated to operate in the manner hereafter described. The spindle of thevalve, which 0 erates vertically in a machine, passes through a suita lestuffing by the machine, such cam plate carrying a v suitablebox at theside of the filling head connected to the main supply ipe 'ofthej box,andis adapted" to be actuated in the i manner hereafter describedby theroller carriedbyl the camplate only when a bottle is in position in theholder.

The'top of the standard is provided with thedistributing head A which is (mnnected to each of the lilling heads (1as hereinafter described. A iixed frame X is provided, to which thesupply pipe B is iixed, a' flexible com'iectionbeing arranged betweenthe frame and the distributing head. The frame A also carries thenecessary cams for operating the valves,

' 'lhebottle holder is of thcusnal construction, having a cup shapedpart a, to receive the bottom of thebottle, carried by a suitablebracket 0 adjustably mountedon the standards (3 carrying the fillinghead (Z and regulating chamber 1:. To the lower part of the. on carriedby the limo 'et 1), a suitablespring; h being arranged in the bracketso-as to maintain the cup in its highest position and thus filling headd. A vertically arranged rod 'i is connected to the extreme end ofthelever g, such rod being connected at its top end to a bell-crankleverpivoted to the cross arm of standard 0 supporting the filling head d, a

cam block or lever 7c providedwith a wedge shaped slot'lis connected'tothe other arm of the belbcrzink lever j and adapted to rest on the topof the spindle m of the discharge controlling valve n, contained inchamber W, in such a mannerthat when the machine is in operation,-theroller o'of the cam plate p is caused to press on-t'hc top of the leveris and thereby depress the valve n and cause the liquid to'fiow to thebottle. When a bottle breaks, the bottle holdera is-immediately rcturncdto its highest position by means of spring 71, the back end of the lever9 con-' nccted thereto being lowered, and, at the same'time, the leverresting on the valve is, by means of-its connections, automaticallywithdrawn to such a position that even should the roller 0 come abovesame it will not operate the valve. The same conditions prevail when theholder is vacant and the iiller out of action.

If desired, instead of operating the bottle holder by hand it may beoperated by foot, one means for effecting ing formedwith a hook f or thelike, adapted to engage a partf' carried by a foot lever f pivotedto-tliepedestal or standard A of the spindle f is pivoteda suitablelever g this being shown'in- Fig. .1, the lower end of the cup spindle fbechamber e in which a hired plunger 5, carried by a hollow supportingstem 6, lsadapted' to slide. The supporting, stem c is screw threadedand cooperates with the bottom of the chamber e so that when the chamberis rotated it is raised or loweredon its support- .ing stem. In order toprovide an air tight joint between the plunger and the cham .QI when adjustcd to the re( ui'red height, the top of the stem may be slightlyreducedas at so'a's-to carry a plate'e adapted to be forced down againstan india rubber ring or washer c arranged above the fixed plungerwhereby the same is squeezed against the side of theehamber e. The meansfor forcing the plate downward may consist of a suitable shaped spindlee passing through a stufling box 6 in the top of the chamber, a lock nutc, or other suitable means, being formed'on, or carried by its inner'o'rlower end, adapted to engage with a thread on the reduced part c of thesu porting stem e A modiiibd form of regulator is shown in Fig. 5, andconsists of the chamber'e and fixed plunger e carried by the hollowsupporting stem e as previously described. The means for obtaimngan a rtight seal between. the chamber and the piston com- .priscs a rubberwasher 8 provided with a flexible'upturned edge t retained in positionagainst the plunger by a plate a and nuts 1). Above the washer s'aquantity of water w is allowed to rest so that when the air from thebottle passes into the upper part of chamber 6 the pressure on the waterforces the flexible edges of the washer against the side of thecylinder, thus obtaining an air tight seal. The capacity of the chamberis regulated by turning the milled. nut efl which is capable ofindependent rotation apart from the cylinder 6, the latter being therebyraised or lowered as desired, or it may be regulated as before describedby rotating the chamber around the supporting stem 6 in which case themilled nut would be dispensed with.- The water w is automaticallysupplied to the chamber as follows, a bottle is fitted in the holder andthe regulating chamber placed in such position that its capacity isgreater than that required to hold the air discharged, thewater rushesup the hollow stem e into the chamber. The supply being cut oil', thebottle is removed, and anyxexcess water above the top-of the stem e runsback to the iilling'head, leaving only just sullicient to enable a sealto be made.

If a more simple construction is desired, the regulator may be formed ina similar manner to the well-known Staull'er lubricator, so that whenthe cylinder is raised the capacity of the vessel is increased and viceversa, suitable means being provided to insure an air tight jointbetween the plunger and cylinder.

The screw down valve (i above referred to,

connecting the regulating chamber to the filling head is so arrangedthat if onl a small bottle is h eing filled, it may be entire closed,and when larger bottles are bein filled'the rate of the flow may beregulated )y opening or closing such valve.

The operation of the device is as follows,

the air displaced from the bottle passes" through the stop down valve ofthrough the hollow supporting stem c into the top part of the re ulatingchamber 0, the capacit of which ias been reviously determine when thepressure 0? air in the regulating chamber equals that of the inflowingliquid,

L filling ceases, and. by this time the table has rotated to a pointwhere the cam plate P of the particular filler is a ain partlyrotated bycoming into contact wit a further part :r carried by the frame A of themachine, causing the valve to close and cut oil the supply of l'luid,the bottle -may then be removedand stop ered in the usual manner.

In on er to prevent the outrush of air from the regulating chambersplashing the contents of the bottle over when the same is being removedfrom the holder, a small nipple y is secured in the lower end of theairpipe in the discharge head, such nipple being provided with a series ofradial openings z soar-ranged that the air on bein discharged is thrownout against the wa 1s of the discharge head instead of directly, intothe bottle as heretofore.

What we claim is 1. In a machine for filling bottles with,

aerated water and the like having a series of filling heads and bottleholders, the combination therewith of means for independently operatingand controlling the discharge opening of each filling head andindependent means for automatically closing any one or more of suchvalves should a bottle be broken or a particular filler be vacant, suchmeans comprising for each filler, a cam plate fixed above the fillinghead, a roller carried by such plate, a cam block or lever upon. whichsuch roller bears at predetermined intervals, said cam block or leverbeing provided with a wedge-shaped slot, a series of levers connectingsuch camblock or lever with the bottle holder, anda valve spindlesliding in such slot whereby should a bottle break or a holder be emptthe cam blockresting on the valve spindle will be withdrawn to such aposition that the cam roller will be rendered in-operative as set forth.
